Fig. T is a View similar to Fig. 3 showing :in :iitrrnativo construction.

Referring to the drawings. the transmission resing of' im automobile is indicated at 5. casing 1'). which comprises a main or body portion and a. rap 7, ent-loses the usual sliding variable speed gears. two of nliirii :iro iiulirated at 8, und is provided with two slidiiiole selector rods 9 carrying the usual forks l() for sliding the gears into mesh. "llie forks 10 are rigidly secured to (Le sliduiile rods i) and the hubs 'il of the forks siro notrlied :it thoir upper sides. as indicated st 12 to be selectivelyv engaged by the lower extremity of the usual change spend lover 13 which has a ball and socket mounting in tlie rap 7 of the transmission fusing. B vsliifting the change speed lever 1?; into operative engagelmnt with on@ or the otl'ior ol: the hubs 11.` the rods 9 and the forks 10 carried thereby may he seieetively actuated to shift the gears. The opposite rods of the srlertor rods 9 slide in bearings l5 in t-lie rop T.

In one form of construction heretofore employed tire bearings for the selector rods wenl rlosed :it their outer ends to prevent oufwurd leakage of oil. lith this construction :zu :1 rod was shifted in one direction. oil which :idliererfl to the exposed portion of the rod u as drawn by suction into the porket formed between one end of the rod and the closed outer end of the respertivo bearing and the rod was shiftd in the opposite direction this oil was nebessarily (lispla ed and forced backwardly into the gear rasingz.

In mundanoswith the present invention, it is proposed to tal-re advantageof this pumpingy artion of the seleetor rods in their lie-:wings to force oil from these bearings and deliver it to the various parts t1 be lubririztoll. For this purpose the outer end of escl] hearing 15 is closed except for an outiet port wliif-la is ronnerted by it small tube with one of the parts to be lubricated and Pimp UML

l k l s muy be u www mili Mh ma rumena" imm www? h will @man in hnmga the :veut the rc Thus when an? av 'n the bem i fr fi fiile valve 38 will open to permit oil to be drawn into the bearing pocket by suction and when the selector rod is moved in the oppposite direction the valve 3H will valve 25 will open to permit the oil to be forced froui'the bearing pocket into the tube 211. .vhich conveys it to the part to be lubricated.

lt may be founf desirable to modify the construction shown in Fig. 3 by eliminating the ball valve, the connection between the oil pocket in the bearing l5 and the oil Iconduit or tube .Z-l being made as shown in Fig. 7 by threading said tube into theI outer end of said bearing. Without the valve, there will be no suction action tending to draw Oil into the bearing but a certain amount of oil will work alon'r the bearing and into the oil pocket, as t e selector rod is repeatedly shifted. and this oil will be displaced from the oil pwgliet into the conduit connected therewith and it will lgradually travel through the conduit to the part. to be lubricated. lt has been Jfound in many instances that an excessive quantity ot' oil is supplied to the parts when the valve construction is employed and that an ample supply may be delivered Without the use of any valves.

The above described device mav be constructed and arranged to deliver the proper quantity of oil for ordinary lubrication ot the different parts of the chassis. Considerable pressure can be produced if necessary without ma'king the gear change appreciably more ditlicult. The operation is inevitable and automatic, and cannot be neglected it' the car is to be operated at all.

'llo the end that the required quantity of oil shall be delivered to the various parts of the chassis the connections to the several bearing pockets should be justly apportioned in order that the movements most irequently made on the change speed lever will force oil to those parts of the chassis which require the greatest amount of lubrication l"or example. on cars which habitually start on second `rear` first being rarely used, the part lubricated by the movement into tirst speed would have to be of secondary importance or requiring oil only in the wintertime when lirst speed has often to be used. The motion into reverse 'gear being needed with considerable frequency,y would be arangred to lubricate a part of greater importance.` ivhihl the nioveinnets intro second. third and hugh `:1e-ar beinpr used most Jfrequently of all, would be used to lubrieatc parts of the lirst importance.

lli.' using brauch tubes leadini l'i'om the main supply conduits 2l or by distributing oil from the valve chambers lll h v means of a suitable number ot' tubes leadingA directly therefrom. thc ivhole of the chassis could be automatically lubricated in the above described manner lt will be desiiable` howbe closed and the ever, to have a transmission case having a considerable reserve supply of oil and to have oil gauge on the case which can easily be read so that it may be replenished when necessary. (ln cars in which the transmission is lubricated from the saine body ot' oil as the engine, this precaution will not he necessary, since the crankchamber of the engine contains a large re'scrve of oil and generally a si fht feed indicator showing.i the quantity of oil in the cranln'hainbei.

The invention has been disclosed herein for illustrative purposes in what isat present considered its preferred en'ibodiment and several modified constructions have als'o been referred to, but it is to be understood that the scope of the invention is detined by the appended Claims rather than by the foregoing description. lt is particula'rly pointed out that while the invention has been illustrated and described in connection u'ith an automobile transmission of the selectivo sliding gear type it is equally applicable for use in connection with transmissions ot' the progressive slidingr gear type or ofthe planetary type inasmuch as both these latter types commonly comprise one or more slidable shafts. which may be utilized to produce the requisite pumping action for supplying the oil. The invention is not, in fact. limited to the employment oi a slidable transmission shaft as the piston and said shalt bearing as the cylinder of the oil pump` it beiner within -the scope ot the invention to employ an oil pump of any type which may be operatively connected with the change Speed lever o." other reciprocalile part of :in automobile transmission.
